TITLE:    The AAA Algorithm For Rational Approximation

ABSTRACT:

With the introduction of the AAA algorithm in 2018
(Nakatsukasa-Sete-T., SISC), the computation of rational approximations 
changed from a hard
problem to an easy one. We've been exploring the implications of this 
transformation ever since. This talk will review the algorithm and then 
present about 15 demonstrations of applications in various areas
including interpolation of missing data, analytic continuation, analysis 
of solutions of dynamical systems, Wiener-Hopf and Riemann-Hilbert 
problems, function extension, model order reduction, 
Dirichlet-to-Neumann maps, and Laplace, Stokes, and Helmholtz 
calculations.
